NASA astronauts Nichole Ayers, Jonny Kim and Anne McClain marked Independence Day with a few heartfelt words for their compatriots here on Earth.

What can the pH level of the subsurface ocean on Enceladus tell us about finding life there? This is what a recent study accepted to Icarus hopes to address as a team of researchers investigated the potential pH level of Enceladus’ subsurface ocean based on current estimates. This study has the potential to help scientists better understand the composition of Enceladus’ subsurface ocean and what this can mean for finding life as we know it.

Distant exoplanets can be dodgy to spot even in the best of observations. Despite the challenges, a team of astronomers just reported the discovery of a gas giant exoplanet that lies about 400 light-years from Earth. It's called TOI-4465 b and it takes 12 hours to transit across the face of its star during its 102-day orbit.

Using data from ESA’s SMOS satellite, scientists have revealed a surprising shift in the Southern Ocean – surface waters around Antarctica are growing saltier, even as sea ice is diminishing rapidly. This finding defies the norm because melting ice typically freshens ocean surface water.

The implications are far-reaching as changes in this remote region can disrupt global ocean currents, affect climate patterns, and alter ecosystems far beyond the Antarctic.

Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this transformation, they may vomit out more stellar material than we knew.

Adult brains grow new neurons, and scientists have finally pinpointed where they come from

What is the importance of studying and utilizing lunar polar volatiles during the Artemis program, and specifically for first crewed mission, Artemis III? This is what a recent study presented at the Lunar and Planetary Science Conference hopes to address as an international team of researchers investigated using lunar polar volatiles for in situ resource utilization (ISRU) purposes. In geology, volatiles are substances that vaporize at low temperatures, and examples include water, carbon dioxide, and sulfur dioxide. In the case of the Moon, key volatiles are water located in permanently shadowed regions (PSRs) at the lunar south polar region.

Quasars provide some of the most spectacular light shows in the universe. However, they are typically exceedingly rare since they are caused by massive astrophysical forces that don’t happen very often. So it came as quite a surprise when scientists found a group of 11 of them hanging on in the same general area, in what appeared to be equivalent to the galactic countryside. A new paper from Yongming Liang and their co-authors at the University of Tokyo describes this finding, which they dubbed the Cosmic Himalayas, and some of the weird astronomical circumstances that place the discovery in context.
